Investing in the stock market can be a rewarding venture, offering the potential for substantial gains. However, with reward often comes risk, particularly when traders and investors use leverage to enhance their purchasing power. One of the key risks associated with using leverage is the margin call, a mechanism that brokers use to protect themselves and their clients from excessive losses. In this article, we’ll explore what margin calls are in stocks, how they work, why they happen, and how investors can manage or avoid them.
1. What is a Margin Call
A margin call occurs when the value of an investor’s margin account falls below the broker’s required minimum level, known as the maintenance margin. A margin account is a brokerage account that allows investors to borrow money from the broker to purchase more securities than they could with just their own capital. The borrowed money is essentially a loan from the broker, and the securities purchased serve as collateral.
When the securities in the margin account decline in value, the investor’s equity (their own money in the account) also declines. If this equity falls below the required maintenance margin level, the broker will issue a margin call, demanding that the investor either deposit more funds into the account or sell off some assets to bring the account’s equity back above the required threshold.
Example of a Margin Call
To better understand the concept, let’s consider a simplified example:
An investor opens a margin account and deposits $10,000 of their own money. The broker allows the investor to borrow an additional $10,000, giving them a total of $20,000 to invest.
The investor purchases $20,000 worth of stocks using this borrowed money.
Now, let’s say the stock price drops, and the total value of the stocks falls to $14,000. The investor’s equity in the account is now $4,000 (since they owe $10,000 to the broker).
If the broker requires a maintenance margin of 25%, the investor must maintain equity equal to 25% of the total value of the portfolio ($14,000 x 0.25 = $3,500). Since the investor’s equity is above the maintenance margin level at $4,000, no margin call is issued yet.
However, if the value of the stocks falls further, say to $12,000, the investor’s equity drops to $2,000, which is below the required 25% ($3,000 in this case). At this point, the broker issues a margin call.
In response to the margin call, the investor must either:
Deposit additional cash to raise the account’s equity above the required maintenance margin, or sell enough securities to reduce the loan balance and bring the equity back to the required level.
Forced Liquidation
If the investor fails to meet the margin call by adding funds or selling assets, the broker has the right to force the liquidation of securities in the account. This means the broker will sell enough assets to restore the account’s balance to the required level, without further notice to the investor. Forced liquidation often locks in losses during market downturns, making it a costly outcome for the investor.

2. Types of Margin Calls
Margin calls can take different forms depending on the specific terms of the margin agreement and the market conditions. The two main types of margin calls are:
Initial Margin Call
An initial margin call occurs when the investor’s account falls below the initial margin requirement, which is the amount of equity the investor must maintain when they first purchase securities on margin. This requirement is typically set by the broker but must comply with regulations from entities such as the Federal Reserve, which mandates a minimum initial margin of 50%.
For example, if the investor wants to buy $10,000 worth of stock, they must have at least $5,000 in equity at the time of purchase. If the value of the account drops significantly, the broker may issue an initial margin call demanding that the investor restore the equity level to the required amount.
Maintenance Margin Call
A maintenance margin call happens when the value of the securities in the account declines after the initial purchase, causing the investor’s equity to drop below the maintenance margin level. The maintenance margin is typically set at 25% to 30% of the account’s total value but can vary depending on the broker.
If the investor’s equity falls below this threshold due to declining stock prices, the broker will issue a margin call requiring additional funds to restore the account’s equity. If the investor cannot or does not meet this margin call, the broker may force the sale of securities in the account to recover the borrowed funds.
3. Why Do Margin Calls Happen
Margin calls are triggered when an investor’s account equity falls below the required margin threshold. There are several reasons why this might happen:
Decline in Stock Prices
The most common cause of a margin call is a drop in the value of the securities held in the margin account. If the value of the stocks declines significantly, the investor’s equity decreases, putting the account below the required margin level. In volatile markets, even relatively small fluctuations in stock prices can lead to margin calls if the account is heavily leveraged.
Over-Leveraging
Leverage amplifies both gains and losses. Investors who borrow a large portion of the value of their account (i.e., use high leverage) are more vulnerable to margin calls. Even a small downturn in the market can cause the account’s value to fall below the maintenance margin, triggering a margin call.
Changes in Broker Margin Requirements
Brokers can adjust their margin requirements based on market conditions or the risk profile of the investor’s account. During periods of heightened volatility or market instability, brokers may raise their maintenance margin requirements. If this happens, investors may receive margin calls even if the value of their portfolio hasn’t changed dramatically.

4. Consequences of a Margin Call
Failing to meet a margin call can lead to several negative outcomes for investors:
Forced Liquidation
As previously mentioned, if the investor cannot or does not meet the margin call by depositing additional funds, the broker will sell some or all of the securities in the account to cover the loan. This forced liquidation can result in:
Locking in Losses: Selling securities during a market downturn may cause the investor to lock in losses that could have been avoided if the stocks had been held for a recovery.
Loss of Control: The investor loses control over the timing and selection of which securities to sell, as the broker makes the decision based on their interests.
Negative Account Balance
In extreme cases, especially during rapid market declines, the value of the securities sold may not be enough to cover the margin loan. This could leave the investor with a negative account balance, meaning they still owe money to the broker even after their account has been liquidated.
Credit and Financial Risk
If an investor is unable to pay back the broker after a margin call and forced liquidation, they may face legal action or damage to their credit rating. This could have long-term financial consequences beyond the initial losses.
5. How to Avoid Margin Calls
Given the potential risks and consequences of margin calls, it’s essential for investors to take proactive steps to avoid them. Here are some strategies to minimize the risk:
Use Less Leverage
One of the most effective ways to avoid margin calls is to use less leverage in the first place. By borrowing less, investors reduce the chances that a decline in stock prices will push their equity below the maintenance margin level.
Monitor Your Account Regularly
Investors who use margin should regularly monitor the value of their portfolio, especially during periods of market volatility. Keeping a close eye on stock prices and account equity allows investors to take action before a margin call is issued, such as depositing additional funds or selling securities voluntarily.
Diversify Your Portfolio
A well-diversified portfolio reduces the risk of large, sudden declines in value. By holding a mix of assets across different industries or sectors, investors can cushion the impact of market volatility, reducing the likelihood of a margin call.
Maintain a Cash Buffer
Keeping additional cash in the margin account can serve as a buffer against market fluctuations. Having extra funds readily available ensures that the investor can meet margin calls without needing to sell assets at a loss.
Set Stop-Loss Orders
A stop-loss order is an automatic sell order that activates when a stock’s price falls to a predetermined level. Using stop-loss orders can help investors limit losses and maintain sufficient equity in the account, reducing the chance of a margin call.
Conclusion
A margin call is a financial warning that can have significant consequences for investors who trade on margin. While leveraging a margin account can amplify returns, it also increases risk, particularly during market downturns. Margin calls occur when an investor’s equity falls below a required level, and if not met, the broker may force the sale of securities, locking in losses. To avoid margin calls, investors should use leverage cautiously, monitor their accounts regularly, diversify their portfolios, and maintain a cash buffer. By managing margin exposure responsibly, investors can mitigate the risks associated with margin trading and protect their financial well-being.
